BIOS dump for a Lenovo laptop built on the NM-C821 motherboard, provided as an 8 MB binary. NM- prefixed board numbers belong to LCFC, the Lenovo-owned ODM that designs many IdeaPad and ThinkPad boards. The name gives no model, revision or version, so verify the NM-C821 label on the PCB first. A raw image like this is written to the SPI flash with an external programmer to recover a board that will not boot; the chip must be 8 MB to accept it, and the original contents should be backed up before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @schematiclaptopramkushwaha. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
